What You’ll Need to Make Cheesy Party Potatoes

• 26 oz frozen hash browns, thawed
• 16 oz sour cream
• 10.5 oz can of cream of chicken soup
• ½ cup (1 stick) butter, melted
• 8 oz cheddar cheese, shredded
• ½ tsp salt
• ½ tsp pepper
• 1 tsp garlic powder

For Topping:

• 2 cups crushed cornflakes
• 6 tbsp butter, melted

How to Make the Cheesy Party Potato Casserole

1. Prep Your Pan and Ingredients

• Preheat your oven to 350°F.
• Grease a 9×13-inch casserole dish with butter or nonstick spray.
• Crush your cornflakes (a zip-top bag and a rolling pin work beautifully).

2. Mix Up the Filling

In a large mixing bowl, combine:

• Thawed hash browns
• Sour cream
• Cream of chicken soup
• 8 oz shredded cheddar
• ½ cup melted butter
• Salt, pepper, and garlic powder

Stir until everything is evenly coated and deliciously combined.

3. Spread and Top

• Spread the potato mixture evenly into your prepared casserole dish.
• Sprinkle the crushed cornflakes evenly over the top.
• Drizzle the remaining six tablespoons of melted butter over the cornflakes (don’t skip this step—this is what makes the topping golden and crispy!).

4. Bake

• Place the casserole in the oven and bake for 1 hour and 10 minutes.
• The topping should be golden, the edges bubbling, and your kitchen will smell like absolute heaven.

5. Serve and Enjoy

• Let cool for a few minutes before scooping. These are best served warm and gooey.

Tips for Perfect Cheesy Party Potatoes

• For the best texture, make sure your frozen hashbrowns are thawed completely. Spread them on a paper towel if they’re a little watery.
• Sharp cheddar packs the most punch, but feel free to use a blend (Monterey Jack, Colby, or even a sprinkle of Parmesan).
• Sprinkle a handful of chopped green onions, cooked crumbled bacon, or even a little diced ham over the top for a heartier casserole.
• Prep the casserole (without the cornflake topping), cover, and refrigerate up to 24 hours in advance. Add the topping and melted butter just before baking.
• These reheat beautifully. Pop leftovers in a 350°F oven for 15–20 minutes, or microwave individual portions.

Make It Your Own: Variations & Add-Ins

This is a base recipe you can truly personalize. Here are a few ways to mix things up:

• Vegetarian Version – use cream of mushroom soup instead of chicken. Add sautéed mushrooms, bell peppers, or spinach.
• Add a dash of cayenne or a sprinkle of diced jalapeños for a little heat.
• Try topping with crushed Ritz crackers or even panko breadcrumbs if you don’t have cornflakes.
• Stir in cooked, diced ham, rotisserie chicken, or bacon for a full meal in one pan.

How to Serve Cheesy Party Potatoes

You can serve Cheesy Party Potatoes right from the baking dish, or dress them up for your table:

• Place your casserole on a trivet with a serving spoon, and let guests help themselves, buffet style.
• Scatter chopped chives, parsley, or even a few extra shreds of cheddar over the top for color.
• Pair with eggs, crispy bacon, and a fresh fruit salad for an extra special brunch.
• These go beautifully with a whole chicken, beef tenderloin tips, or a classic Salisbury steak.
• Tuck into your holiday spread alongside turkey, ham, or prime rib.

Serving Tip: If you want your table to feel special, use a pretty casserole dish and add a linen napkin beneath the pan for an instant upgrade. (A classic white Staub or Emile Henry baker always looks gorgeous!)

Hosting Tips to Make Your Gathering Effortless

If you’re serving a crowd, here are a few ways to keep it simple and stylish:

• Mix and assemble the casserole the night before. On party day, add the topping and bake.
• If you’re serving buffet-style, set the dish on a warming tray or in a low oven (around 200°F) until ready to serve.
• This dish travels well. Wrap tightly with foil and reheat at your destination.

Little Luxuries to Elevate Your Cheesy Potatoes

If you want to give this classic casserole a little something extra, here are a few subtle upgrades:

• Use a high-quality European-style butter for richer flavors.
• Aged cheddar or a blend of white and yellow cheddar can make the flavor pop.
• A sprinkle of fresh thyme or chives over the finished dish adds a hint of elegance.
